Ive been looking into doing more car audio on my personal vehicle and maybe some side work and i want to pickup a copper lug crimper tool. All i have used in the past making welding leads, is the small black one that u have to use a sledge and hammer the press to crimp the lug. Ive seen some that were like bolt cutters that have a crimp die on the end. Anyone used these before or how about a small hydraulic press type. Both ate around $40 on ebay. Here is the link to the hydraulic type. http://m.ebay.com/itm/Hydraulic-Crimping-Tool-Kit-10T-Cable-Crimper-Dies-Wire-Terminal-Crimp-Lug-Set-/191938008091?nav=SEARCH
